IMPROVED APPARATUS FOR SUPPLYING LIQUOR T0 CENTRIFUGAL MACHINES.

Specification forming part of Letters Patent No. 58,864, dated October 16, 1866.

To all whom it may concern:

Be it known that I, WALTER R. MEINS, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Liquoring- Bucket for a Centrifugal Sugar- Bleaching Machine; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

The invention relates to the process of liquoring sugar in centrifugal sugar-bleaching machines.

In the process as usually practiced with these machines the liquor is introduced to each one of a series of centrifugals from a vat or tank common to the series, and it is impracticable to obtain uniform results from the different machines, from the fact that each attendant is not only ignorant of the amount of liquor he draws for the successive charges of sugar in the centrifugal, but has no means of comparing the work of his machine while in operation with the work of the others of the series.

In the process of liquoring as practiced by me I employ a separate liquor-bucket for each centrifugal, and so construct this bucket with a gage that the attendant at each machine has directly under his observation the amount of liquor drawn into the centrifugal, and is thus enabled to regulate the quantity drawn, and having ascertained by experiment the amount necessary to produce a certain result, the same result may be successively obtained with the same machine, and a uniform result with the whole series.

The invention consists, therefore, in a portable liquor-bucket having a liquor-denoting gage upon its outer surface, by which the flow from the bucket may be observed and regulated as circumstances may require.

The drawing represents a view of a bucket embodying my invention.

a denotes the liquorcontaining vessel, made open at the top, and provided with handles 6, and having a flexible eduction-pipe, 0, provided with a rose, d. Leading from or near the bottom of the vessel is a short pipe, 0, having a glass tube, f, extending up from it, this tube being marked with a scale, so that the level of the liquid within the vessel may be observed by reason of its corresponding level in the tube, and its height read from the scale. This bucket is placed in proximity to the centrifugal machine, into which its liquor is to be drawn, and at such height with respect thereto as to discharge its contents into the centrifugal.

Now, it will be obvious that if, while the centrifugal is running at a certain speed, it is found that a certain number of inches of liquor drawn from the bucket produces the nquired result in removing the sirup from the sugar, the same result may be successively obtained by the attendant without any other skill than that necessary to observe the quantity of liquor used for the first charge, and to draw the same quantity for each charge, and that by thus ascertaining the result effected by a certain quantity at one machine, all the machines of the series may be made to produce a eorrespondin g and uniform result.

In drawingto all the centrifugals from a common tank by the old process not only is there no certainty of a uniform result, but a great waste of liquor occurs from the amount liable to be used in excess of what is required to wash the sugar, while the quality of sugar is also impaired by the excessive use of liquor, all of which disadvantages are overcome by the method of liquorin g practiced by me.

I claim- For use with a centrifugal sugar-bleaching machine, a portable liquoring-bucket having a construction substantially as described.

WALTER R. MEINS.
